Because there is an opportunity cost to having an SD slot. Remember it takes up physical space inside the device, which could be used for more internal memory, battery space etc. they would have opted for something everyone wants over a smaller subset of users

There are opportunity costs for everything, but microsd readers are a cheap, mature, commodity technology that's been in top-end phones for ages, its impact on the phone's available real-estate for battery and memory is nearly negligible.

That sounds more like an engineering challenge than a UX compromise. Also, as these heated threads show, what "everyone wants" is a bit elusive. I think they could overcome these "costs" if they wanted, but they don't -- the actual UX "cost" of complicating how the user interacts with storage is probably one reason why.
